Mipro ISM MI-58 Wireless IEM 5.8GHz System 

Front of the Mipro MI-58 In-Ear Monitor System

Just like its big brother the Mipro MI909, the MI-58 will be a superior system when compared to what else is in the market in the under $700 range.  The build is solid and professional. When I compare the competition, I always find myself looking at a component and thinking, "Well this is Mickey Mouse." No such parts on the MI-58 - Solid and well built. When you look at the MI909 page on my site, you will see lots of parts. That is all that ever goes wrong Mipro. Lost antennas, knobs, belt clips etc. The systems are built to last. I still have plenty of clients around the world still using the discontinued 808TR analog system 20 years later.


The MI-58 system is fully digital. With the 5.8GHz frequency range, I was unable to find a channel that was not open (this was a real treat). 


Better Frequency Range - Bass players check this out. Due to the wider bandwidth, the frequency range is greatly expanded to 20Hz-23kHz. For comparison, the Sennheiser G4 is 25Hz-15kHz, the Shure PSM300 is 25Hz-15kHz and the Shure PSM900 is 38Hz – 15kHz.


The MI-58R Belt pack is the industries smallest, most lightweight fiberglass reinforced on the market. Granted, if you are the size of Andre the Giant, that is not relevant. But let us say you are one of those players that keeps the belt back in a pocket (heaven forbid) or, a female singer that needs to clip in under a dress or theater groups where belt pack real estate is tight. The MI-58R Belt pack is a game changer. The MI58 Belt Pack is powered by one ICR18500 Li-ion Rechargeable battery and has a backlit LCD screen. The latency is 2.2ms (REAL LOW). 


The MI-58T Transmitter is housed in a half space metal case with an OLED Display Screen. Audio sampling has a 24-bit / 48kHz Rate. An available option is a RJ-45 DANTE interface.


Range: My warehouse is 150 feet long and I never walked out of the signal. The volume and clarity stayed consistent throughout my warehouse.


I would recommend some additional batteries that you can have charged as backups. I did notice a drop in performance right at the batteries life. And like any other IEM system, a freshly charged battery before your show is simply good practice.


IS THE MIPRO MI909 A BETTER SYSTEM? MI-58 advantages, In the 5.8GHz Freq Range, EVERY channel was open. That was quite a treat. I'd say the MI-58 System is well suited for one, two three player bands.  When the number of wireless channels is higher, the MI909 is the way to go. The MI909 has antenna combiners, splitters, and antenna paddles (the MI-58 does not). The MI909 is Mipro's top of the line touring rig and I'd stack it up against anything on the market. The MI58 was made to compete (and eat the lunch of) the lower priced Ear Systems on the market. PSM300, Galaxy, Carvin, CAD etc. When your budget is in this area - the MI-58 is a clear winner. If you have the $749 to spend the MI909 wins over the Sennheiser G4 and the Shure PS900.

So here's the question, do you need all those bells and whistles of the higher end systems? If the answer is no, the MI-58 buy it now link is below.

Mipro FBC-71  Back to Front Antenna Extender for MI58

  MIPRO is telling us the FBC-71 is not the right rear to front antenna kit for the MI58T.  It can attenuate the RF signal which would reduce range.  We do have the FBC-72 which is a new rear to front kit for the 5.8 ISM products on order and they should be leaving the factory the 24th of May.
